HandyWaiter - Dumbwaiter
Drawing inspiration from our ultra reliable WoodWaiter, WB Fowler Industries also produces the multi-purpose electrical HandyWaiter, a dumbwaiter that is able to travel as much as 40 feet vertically. We have designed the electric dumbwaiter to lift 200 pounds at a speed of 28 feet per minute. The car is always custom built to suit our customer's needs. The car floor may be as low as 34 inches above the existing floor at it's lowest level.
The shaft area, where the lifting device operates, must be lined with fireproof material. The car is moved up and down the track by means of a low maintenance number 40 roller chain with a 3125 pound burst strength. We do not use a drum and cable system which is much less reliable than chain and requires the mechanism be located above the car at the top of the hoistway. Adjustable limit switches stop the car at each level. A safety brake is built into the car in case of an unforeseen loss of lift.
The HandyWaiter dumbwaiter track is built in 6 foot sections with the first section of track holding the motor, gearbox and main electrical control panel.
WB Fowler Industries has manufactured HandyWaiters as a perfect vertical lift solution for many locations:
- Restaurants with multi-floor dining
- Private Clubs for drinks service
- Retirees for grocery lift up flights of stairs
- Flood zone areas where structures are built on pilings
The HandyWaiter is ideal for coastal homes that are built on pilings. The motor, gearbox and main 120v AC electrical control panel can be relocated to the top of the hoistway and out of the way of water at no extra charge. All control panels (min. 1 per access door) operate on 24v AC.

Installation Instructions for both Top & Bottom mounted motors
- Before installing the HandyWaiter please make sure that the hoistway shaft walls are lined with a fireproof material adequate for your local zoning bylaws. 5/8" drywall is usually sufficient for most areas. Make sure the track side wall of the shaft is first lined with 3/4" plywood underneath the drywall to anchor the track lag screws.
- Install the first modular section. This section should be secured central of the track side of the hoistway wall. The following numbered sections stack and interlock on top of each other to the top of the shaft and must also be secured to the hoistway wall.
- Carefully unroll the chain that is located in the car. Thread the chain over the top sprocket, being careful not to twist it, to the bottom of the unit. To make this easier, now lift the car approximately 12 inches and install the chain around the bottom sprocket so that the weight of the car is resting on the chain, this allows easier installation of the threaded rod into the 5/16” hole on the bracket of the car. Now install the washer and nut and tighten the tensioning spring until all the coils are touching. Again check that there are no twists and that the chain is roughly parallel to the track. Then cut the zip tie holding back the car's safety brake.
- The Master control panel is attached to the motor via a large black power cord. It should be mounted on the wall just outside the hoistway. Power is 120 volt and should be on a separate dedicated 15-amp circuit breaker. The 24-volt control panels are attached via connectors that are numbered. By connecting like numbers you can complete the installation of all the control panels.
- Install the universal electric door locks & door safety switches as indicated on the enclosed diagrams.
- Feel free to call anytime with any questions.
Once a year the lift chain should be lightly oiled. A motorcycle chain lube in an aerosol spray can works well. Make sure the power is off and the car is at the bottom of the hoistway before lubricating the chain.
